OTOOOBTS. 31<) 



Genus OTOCORYS, Bonap., 1838. 



The genus Otocorys contains the Horned Larks, three species of 

 which are found at considerable altitudes in the Himalayas. They 

 occur in Hocks, and at the breeding-season the males arc said to rise 

 in the air, and sing in the same manner as the Sky-Lark. 



The Horned Larks have a few lengthened feathers springing 

 from each side of the crown in both sexes. The bill is of median 

 length, and the nostrils are densely covered by plumes ; the wing has 

 nine primaries, of which the first reaches nearly to the tip of the 

 wing ; the hind claw is straight and about as long as the hind toe. 

 The sexes are slightly different in colour, and both sexes undergo 

 a considerable variation of plumage according to season, caused by 

 the gradual wearing away of the margins of the feathers in winter 

 and spring.
